22 de ago. de 2024 · James Franck was a German-born American physicist who shared the Nobel Prize for Physics in 1925 with Gustav Hertz for research on the excitation and ionization of atoms by electron bombardment that verified the quantized nature of energy transfer. Franck studied at the universities of Heidelberg.

17 de ago. de 2024 · German physicists James Franck and Gustav Hertz confirmed the existence of quantum states in atoms in experiments reported in 1914. They made atoms absorb energy by bombarding them with electrons. The atoms would only absorb discrete amounts of energy from the electron beam .
Hace 5 días · After brief training in Berlin, Hahn, together with physicists James Franck and Gustav Hertz, was sent to Flanders again to scout for a site for a first gas attack. He did not witness the attack because he and Franck were off selecting a position for the next attack.
Hace 3 días · By 1914, experiments by physicists Ernest Rutherford, Henry Moseley, James Franck and Gustav Hertz had largely established the structure of an atom as a dense nucleus of positive charge surrounded by lower-mass electrons. [50]
